Aunt Pat Kaepernick, in New London, has a photo of young Colin and her son Brett posing outside Lambeau Field in their Brett Favre jerseys. WLUK-TV says the 49ers quarterback lived in Fond du Lac until he was four and his family moved to California. Extended family remain in Wisconsin.

And while Kaepernick grew up as a Packers fan, Green Bay quarterback Aaron Rodgers cheered for the 49ers as a boy. Rodgers grew up in Chico, about 3 hours northeast of San Francisco.
